To do in D-FW for Monday: Party with tuba players, race a T-rex, mingle with singles and more

TubaChristmas gatherings, like this one in Missouri, are held across the country.

Looking for something to do on Monday? We’ve got you covered!

TubaChristmas:Tuba and euphonium players break out the big brass during a Christmas concert at Thanks-Giving Square, one of many such events held across the country. Plus, there’ll be food trucks on hand before the music starts. This year’s performance is dedicated to the memory of the late Alex Burton, the longtime master of ceremonies for local TubaChristmas events.

Holiday at the Arboretum:Check out the exhibition of 15 otherworldly, colorful Chihuly glass installations in the gardens before its gone (the last day is Dec. 31). Other attractions include hundreds of Nativity scenes from around the world at the DeGolyer Estate and the “Small Houses of Great Artists” exhibit of mini houses throughout the grounds.

Visit the Perot Museum of Nature and Science:The new museum is packed with fun stuff to do, and it’s open from 10 a.m. to 3 p.m. on Monday. Organizers highly recommend buying tickets in advance online. You can race a T-rex (I lost, I blame improper footwear), be shaken up on the earthquake simulator, see an 85-foot Alamosaurus and much more.

Matzoh Ball 2012: The event for ages 21 and up is billed as the biggest Jewish singles party of the year. Head for eM The Venue for the bash, which features a cash bar, music, a photo booth and kosher snacks.

Scrooge Puppet Theatre:The curmudgeonly Scrooge puppet, known for giving attendees a hard time during this NorthPark Center show, might just have a change of heart today.
